Earth the third of the nine planets, surrounded by an atmosphere is the only planet in the universe that supports life, therefore, there is a need to conserve it to
ensure it remains sustainable. The concept of Earth Day was first initiated during a
UNESCO conference in San Francisco, USA by John McConnell in 1969 where he
proposed the first day of spring in the northern hemisphere on 21st
March referred to as Vernal Equinox the time when the Sun crosses the equator
making the length of night and day equal in all parts of the Earth.to be
commemorated. A month later a separate Earth Day was founded by United States
Senator Gaylord Nelson as an environmental teach-in first held on April 22,
1970 which was thereafter launched internationally as a day to create awareness
and focus on combating environmental issues.
Earth Day as an
environmental movement has been celebrated globally on 22nd April for
over 40 years now with a variety of activities to promote environmental
awareness and identify ways to improve our environment and make a difference. This
is now coordinated globally by the Earth Day Network. The global theme for this
year 2013 is “The Face of Climate Change".
Earth Day |
Every day should be
set out by people all over the world as a day of action to positively influence
human attitudes and provoke policy changes with regards to effects of climate
change and control measures to mitigate them.
The
climate plays such a major part in our planet's environmental system that even
minor changes have impacts that are large and complex.
Climate
change refers to the changes in the statistical distribution or properties of
the climate system when considered over a long period of time. The major
concerns of climate change are not the natural earth processes causing changes
in the atmosphere but man’s activities that alter the environment bringing
about changes in the ecosystem.

Climate change and its impacts:
Global Warming: Increasing
temperature of the earth surface (average air) and water system (ocean
temperatures) due to green house gases and depletion of the ozone layer leading
to melting of the polar region and Arctic sea ice. Studies since 1961 show that the average
temperature of the global ocean has increased to depths of at least 3000m and
that the ocean has been taking up over 80% of the heat being added to the
climate system.
Unpredictable effects on the world's water systems: Due to the
increasing levels of seas, a lot of areas are now prone to floods. In Nigeria
for examples the northern states that are normally drier are experiencing
floods leading to displacement of residential home, destruction of farmland,
erosion. Increasing extremes of drought and flooding have become very common,
causing displacement, erosion and conflict and less fresh water means less
agriculture, food and income.
Deforestation: Trees help to purify
the air, improve water quality, keep soils intact, provide a source of food,
wood products, livelihood, medicines, and a habitat to most of the world’s most
endangered species. Forests also help protect the planet from climate change by
absorbing massive amounts of carbon dioxide (CO2), a major source of pollution
that contribute to climate change. The increasing rate of deforestation by
logging and burning to clear land for agriculture, livestock and construction
releases huge amounts of carbon dioxide and other harmful greenhouse gases into
the atmosphere (estimated at 20 percent of global emissions).
Food security: There is a significant
risk of increased crop failure, loss of livestock and local food security. In
some areas with extreme drier/warmer or wet conditions predicted, inconsistency
of these changes will affect agriculture practices thereby affecting
agricultural production, human health and livelihoods, as well as people’s
purchasing power, food markets and food security on a household level.
How Can I
participate?
This
is a clarion call for all. As individuals; adopt more sustainable lifestyle,
monitor your carbon footprint, purchase greener alternative products, use
sustainable transportation, reduce human emissions of green house gases, plant
trees to expand forests (reforestation), use renewable energy sources and
promote energy efficiency. As government or inter-government, adopt cleaner
technologies, set temperature targets, emissions tax, carbon trading, and
implement environmental strategies and policies.
What action plan do we have as individuals, organization or the government to combat these imparts, are there are controls we can use to minimize the effects of climate change? Take an action today! The earth is our heritage, let us ensure we adopt greener lifestyles and sustainable activities to ensure we conserve the environment for future generations.
